A manual strapping tool for joining overlapping portions of a thermoplastic strap includes a cantilevered spring having fixed and vibratory ends. The fixed end is rigidly anchored to a base member and the vibratory end supports one of a pair of jaws having opposing strap gripping surfaces. The other jaw is fixedly positioned on the base so that the strap gripping surfaces are normally in confronting engagement. An operating handle is pivotally mounted on the base member and swingable from a start position through a strap compressing position and a strap sealing position. In the start position, a lifter cam on the operating handle engages a lift arm causing the arm to raise the vibratory end of the cantilevered spring and to separate the strap gripping surfaces so that overlapping strap portions can be inserted therebetween. As the operating handle is swung from the start position to the strap compressing position, the lifter cam is disengaged from the lift arm releasing the vibratory end to compress the overlapping strap portions between the strap gripping surfaces. Further movement of the operating handle into the strap sealing position causes a triggering cam means on the operati…
